  1. Plume Diagnostics for Combustion Stability

    SBC: SIERRA ENGINEERING, INC.            Topic: T901

    Sierra Engineering Inc. and Purdue University propose to develop a non-intrusive plume instrument capable of detecting and diagnosing combustion instability. This Stability Diagnostic System (SDS) will be designed, assembled, and tested during this effort. The SDS will include a high-speed video camera and multiple photodiode detectors for observing the plume. It will also include a software pa ...

  2. Non-Axisymmetric Infrared Plume Tomography for Rocket Plume Species and Temperature Distributions

    SBC: SIERRA ENGINEERING, INC.            Topic: N/A

    Spatial uniformity within combustion devices, especially circumferential, is extremely important to the reliability and durability of a liquid rocket engine. Conventional combustion diagnostics, e.g. pressure and thrust, characterize global engine behavior, but provide no direct information about thermal and species distributions across the engine. Sierra Engineering has shown that exhaust plume m ...
